Show that when the poles of a second-order section with transfer function [H(z)=d+frac{gamma_{1} z+gamma_{2}}{z^{2}+m_{1} z+m_{2}}] are complex

Question:

Show that when the poles of a second-order section with transfer function

\[H(z)=d+\frac{\gamma_{1} z+\gamma_{2}}{z^{2}+m_{1} z+m_{2}}\]
are complex conjugate, then the parameter \(\sigma\) defined in Equation (13.74) is necessarily real.
